On October 5, two Russian drones sank a Turkish-owned grain ship about 30 nautical miles off Romania's coast, inside a NATO member's economic waters, killing the captain. Moscow's defence ministry called it retaliation for Ukrainian strikes on Russian refineries and Black Sea shipping, and the next day drones hit two more cargo ships off Bulgaria.
Russia's air campaign over Ukraine peaked on October 8. A guided bomb killed at least 30 people on commuter buses in Kramatorsk, jet-powered drones that Ukraine now intercepts barely half the time struck central Kyiv, and the two-day toll across the country reached 78 dead.
On October 9, Ukrainian drones closed all four Moscow airports for hours and forced the aircraft Putin was travelling on to divert to St. Petersburg. The same day Trump announced he was lifting sanctions on Russian diesel to bring down fuel prices before the November midterms, and the Treasury issued a temporary export license within hours.
Zelensky called the decision weak and said it would hand Moscow billions to fight harder. Trump answered on October 10 that Ukraine should stop hitting Russian refineries and needed a new president, and thanked Putin for the diesel arrangement hours after a Russian strike on Zaporizhzhia killed at least 20 people.
On October 11, Trump declared on Truth Social that Russia and Ukraine had agreed to stop striking each other's energy systems, repeating a claim Moscow had rejected a month earlier. The Kremlin did not confirm it, Zelensky said he learned of it from the post, and within hours a Russian drone hit a Kyiv power plant and a second strike cut power at a Kharkiv station.
Kyiv's answer was conditional. Ukraine will halt refinery strikes only if Russia halts strikes on Ukrainian energy, with the pause reciprocal and guaranteed.
